Summary of Clinical Use
Used alongside behavioural therapy in the management of opiate addiction in patients who have already undergone detoxification, and alongside behavioural therapy in patients with alcohol dependency.
Mechanism Of Action and Pharmacodynamic Effects
Naltrexone antagonises the activity of the opioid receptors in the brain which play a role in addiction. This is postulated to ameliorate the urge to drink in people accustomed to large amounts of alcohol.
